Beautiful, able to watch sunset in chair by edge of water, rooms sound proof, pool was nice size, staff friendly.

We loved the luxurious, relaxing atmosphere and beautiful summer vibe. The beach house was spacious, beautifully presented, and equipped with everything we needed. The stunning beach, lovely resort facilities, convenient parking, and nice bar made it the perfect place to unwind and enjoy the Florida Keys.
Absolutely nothing!

Great location and lovely landscaping and cottages
NO WiFi the entire 4 day stay and non-functioning TV in the main room of cottage 72 during the entirety of the stay, in spite of daily requests to the front office staff to have it fixed.
Other than Otis, lovely and responsive, the ladies at the front desk were marginally interested and took no action. Our stay was during the World Cup finale and we had to sit at the Tiki Bar to watch some of the game. Inexcusable - such an easy fix to accommodate a repeat customer.
